Q: Do you provide both consumer-grade and industrial-grade LCD displays?
A: Yes. We provide consumer-grade, commercial-grade, and industrial-grade LCD displays. Products can be selected according to operating environment, working hours, temperature requirements, and brightness requirements.
Q: What is an LCD display?
A: LCD (Liquid Crystal Display) is a flat-panel display technology widely used in industrial equipment, medical devices, consumer electronics, automotive systems, and smart home products. LCD displays require a backlight to produce images.
Q: What is the difference between LCD, TFT, and touch screens?
A: LCD is the general term for liquid crystal displays. Most modern LCDs use TFT technology for better image quality and faster response speed. Touch screens are divided into capacitive and resistive touch panels depending on the application requirements.
Q: What is the difference between TFT LCD and OLED?
A: TFT LCD uses a backlight to display images, while OLED is self-emissive and does not require a backlight. TFT LCD generally offers higher brightness and longer lifetime, while OLED provides higher contrast and deeper blacks.
Q: What is IPS LCD?
A: IPS (In-Plane Switching) is an LCD technology that provides wider viewing angles, better color consistency, and improved image quality compared with standard TN displays.
Q: What is the difference between IPS and TN displays?
A: IPS displays provide wider viewing angles and better color performance, while TN displays are lower cost and have faster response times. IPS is generally preferred for industrial and high-quality display applications.
Q: What is display resolution?
A: Resolution refers to the number of pixels on the display screen, such as 128x64, 240x240, 480x272, or 800x480. Higher resolution provides sharper and clearer images.
Q: Besides LCD displays, what customization services do you provide?
A: We provide one-stop customization services including PCBA driver board development, hardware circuit design, housing customization, mechanical structure development, and complete device assembly.
Q: What does PCBA customization include?
A: PCBA customization includes driver board design, firmware development, interface modification, circuit debugging, function expansion, and compatibility optimization with your main control system.
Q: Can you customize housings and mechanical structures?
A: Yes. We support customization for plastic housings, metal enclosures, mounting brackets, waterproof structures, surface coating, silk-screen logo printing, and other mechanical parts.
Q: Do you support OEM and ODM services?
A: Yes. We support OEM and ODM projects including product design, prototype development, mass production, branding, and complete assembly services.
Q: What is the operating temperature range of your LCD displays?
A: Consumer-grade displays typically support 0°C to 50°C, industrial-grade displays support -20°C to 70°C, and wide-temperature versions can support up to -40°C to 85°C.
Q: What brightness is recommended for outdoor LCD displays?
A: Indoor applications generally require 300–500 cd/m² brightness, semi-outdoor applications require 800 cd/m² or higher, and direct sunlight environments usually require 1000–1500 cd/m² high-brightness displays.
Q: What is a sunlight readable display?
A: A sunlight readable display is designed for outdoor or high ambient light environments using high-brightness backlights, optical bonding, anti-glare treatment, and IPS technology.
Q: What is optical bonding?
A: Optical bonding is a process that removes the air gap between the LCD and touch panel to improve visibility, reduce reflection, and enhance durability.
Q: Can touch functionality be integrated with the display?
A: Yes. We support capacitive touch panels, resistive touch panels, optical bonding, and various cover glass treatments including AG anti-glare, AR anti-reflection, and AF anti-fingerprint coatings.
Q: What is the difference between capacitive and resistive touch panels?
A: Capacitive touch panels support multi-touch and offer better clarity, while resistive touch panels are pressure-sensitive and generally lower in cost.
Q: What display interfaces do you support?
A: We support RGB, LVDS, MIPI, SPI, HDMI, MCU, and other common interfaces
Q: What is the difference between SPI and RGB interfaces?
A: SPI interfaces use fewer pins and are suitable for smaller displays, while RGB interfaces support higher refresh rates and larger displays with better performance.
Q: Do your LCD displays support STM32?
A: Yes. Most of our LCD displays support STM32 microcontrollers through SPI, RGB, FSMC, and LTDC interfaces. Initialization code and technical support are available.
Q: Can LCD displays work with Arduino?
A: Yes. Many LCD modules support Arduino platforms through SPI or I2C communication.
Q: Can existing LCD displays be replaced directly?
A: Most models support Pin-to-Pin compatible replacement. We can also customize compatibility according to the original interface, size, connector, and circuit requirements.
Q2: Can you provide samples? Is there an MOQ requirement?
A: Yes. Sample testing is supported with no minimum order quantity for standard samples. MOQ for mass production depends on the product type and customization level.
Q: What is the lead time for standard and customized products?
A: Standard stock products usually ship within 1–2 weeks. Standard production orders typically require 3–5 weeks, while PCBA, housing, and ODM projects usually require 6–8 weeks.
Q: What is the lifetime of LCD displays?
A: Consumer-grade LCD displays typically have a backlight lifetime of more than 20,000 hours, while industrial-grade displays can reach 30,000–50,000 hours.
Q: Do your LCD displays support outdoor applications?
A: Yes. Outdoor display solutions can include high brightness, UV-resistant materials, optical bonding, wide-temperature support, and anti-glare coatings.
Q: What warranty services do you provide?
A: Standard products typically include a 1-year warranty. Customized PCBA, housing, and complete-device projects follow agreed contract terms. Non-human quality issues can be supported with repair or replacement services.
